In drill, I think this process is reciprocal and continuous. If things go
right, the whole unit resonates and begins to operate "in the zone." Hence,
"successful marching takes more than just knowing the steps; it requires a
kind of group cohesiveness that has to be performed to be felt." (Salovesh).
Actually, it sometimes feels as if the team is a single organism. My guess
is that one of the reasons oblique moves are difficult to execute is that
they tend to break up the "synergy." Screw-ups dissolve the *illusion* that
the group is acting as one. Individuals come to the fore again. This shift
in perception feeds the laughter that follows blown commands.

There's something important very important in this. But here's my question.
Is it the *repetition* or the *rhythm* that links up with the emotional
center? All rhythm is repetitive, but not all repetition is rhythmic. If
the link is through rhythm, then simply repeating or modelling cognitive
activities may provide no special lift (beyond its contribution to the
learning process itself).

This is not to deny the emotional satisfaction that comes with solving
puzzles. Obviously, this is a great stimulus to learning.

Or could there be "rhythms" to the kind of cognitive interactions (e.g.,
teacher-student) that you refer to above? If so, might they help explain why
some teachers seem to be more effective than others -- they don't miss a
beat? Or are teachers and learners "made" for one another -- sharing a
common cognitive rhythm?
